“…The social sciences are more heterogeneous and less consensual than the physical sciences: priorities are unrealistic. Astronomy, which we are trying to emulate, is a single discipline with about 4,000 researchers; organizationally, it is cohesive; research problems in the field are interlinked so that knowledge in one specialty builds upon knowledge in several others; the extension of knowledge depends upon expensive equipment that is available to any researcher on a competitive basis (Boyce, 1984;Lankford, 1984). By comparison, the social sciences are a sprawling collection of a dozen different disciplines with little cohesion or sense of common purpose.…”
